Limitations
Full ESS is not supported
The Multi RS does not yet support all grid codes, and therefore does not yet fully support ESS in all installations.
See ESS features topic for more details.
Note: For off-grid operation, and for preventing grid or generator feed in, the ESS mode should be set to "Keep Batteries Charged".
Assistants and advanced controls are not supported
The Multi RS will not support VE.Configure assistants programming. Customisation and controls are currently limited to what is displayed in the settings in VictronConnect. You can use the Multi RS demo mode in VictronConnect to see what features are currently available. We expect additional similar control functionality to be added over time to VictronConnect.
Parallel units are not supported
The Multi RS does not support units in parallel. It is not yet known if the current hardware revision will be able to support parallel configurations via a firmware update in the future.
Maximum charging power limitations
The Multi RS is able to charge the batteries from 2 sources, AC input, and AC output with an AC PV inverter.
Maximum charge current from AC sources is shown in the graph below. For example 88 A (DC) at 230 VAC and 57.6 VDC battery voltage.
Combined maximum total battery charge current from AC sources is 100 A (DC).
There is an additional AC current limit that restricts the inverter current to 25A (AC) after approx. 4 minutes, so it is possible to start-up bigger loads
The maximum charging power from an AC supply is 5000W at 230Vac. Increasing the AC voltage will slightly increase this power limit, and decreasing the AC voltage will decrease it.
This is a MAXIMUM theoretical charging current, and additional limitations such as ambient temperature and airflow will also reduce real world output.
AC2 output is not programmable or relay controlled
AC2 output is internally hard wired to the AC input. There is no internal relay contact switch that is able to disconnect, or reconnect it via programming. There is also no delay from when the AC input is connected to when it flows through to the AC2 output.
